Dear mike:I have not see you for a long time.Please let me tell you a thing.
　　
　　Today,we visted a farm.Early in the morning we met at the school gate and went there together.The farm workers gave us a warm welecome.Then the head of the farm showed us around.How glad we were to see the cross and vegetables growing well!At noon we had a picnic lunch in the sunshine.After a short rest,we had great fun singing and dancing.but,the time passed quickly.Before we knew it,we had to say goodbye to the workers.
